Galaxy Populations in Massive Galaxy Clusters to $z$ = 1.1: Color Distribution, Concentration, Halo Occupation Number and Red Sequence Fraction

Galaxy Populations in Massive Galaxy Clusters to $z$ = 1.1: Color Distribution, Concentration, Halo Occupation Number and Red Sequence Fraction

We study the galaxy populations in 74 Sunyaev Zeldovich Effect (SZE) selected clusters from the South Pole Telescope (SPT) survey that have been imaged in the science verification phase of the Dark Energy Survey (DES). The sample extends up to $z\sim 1.1$ with $4 \times 10^{14} M_{\odot}\le M_{200}\le 3\times 10^{15} …
